The trachea is a tube leading to the lungs and its job is to filter the incoming air.
The lungs are located at the end of the trachea and are used to breathe in air, sort through the gases breathed in for oxygen for the rest of the body.
The diaphragm is below the lungs and causes the lungs to expand and contract causing air to come in and out of the lungs.
The epiglottus is at the top of the throat and stops food and drink from getting into the air pipe while eating.
The larynx, also known as the "adam's apple," protects the trachea and allows us to make sound.
The vocal cords are located inside the larynx and produce sound.
A cell's job inside the trachea is to stop particles from getting to the lungs. The cilia grab onto the small particles and trap them in the goblet cells full of mucus. Having the columnar shape with the cilia on top and the goblet cells underneath them makes it a very efficient way of trapping and placing the particles in the mucus.
THE BREATHING PROCESS
When the air reaches the lungs it goes through the bronchi and bronchioles to the aveoli. Oxygen passes through the wall of the aveolus and into the blood in small capillaries. Once in the blood, red blood cells take the oxygen to the heart where it can be sent throughout the body. After all the oxygen has been used up, the blood comes back carrying CO2 and other waste and goes back through the aveolus wall. From there the waste goes back through the bronchioles, bronchi, trachea, and out through the mouth.
Body System Checklist - Respiratory System ü Major functions of respiratory system
ü Describe how the structure of a cell inside the trachea (pseudostratified columnar epithelium tissue) provides an advantage on its function. (include goblet cells and cilia and what they do)
ü Explain the major parts - trachea, lungs, diaphragm, epiglottis, larynx, vocal cords – and list the function(s) of each. Include a picture/diagram
ü Describe the “breathing” process. o How is the diaphragm used to inhale and exhale? o How and where do you get oxygen and get rid of carbon dioxide? (include what happens at the alveoli here-look up gas exchange).
ü Explain what COPD is. What are some risk factors that contribute to COPD? What are some types of COPD?
COPD is Chronic Obstructive Pulmanry Disease. COPD damages lumgs making it harder to breathe. It causes scarring of the lung tissue. Some factors that contribute are smoking, people whose mothers smoke during pregnacy. It affects lung growth and development. COPD includes conditions such as bronchitis and emphysema.
ü Find 4 fun/interesting facts about your body system. You may list the facts as sentences or use them to create trivia questions.
1) Each minute you are breathing in about 13 pints of air.
2) Resting heart rate is usually between 72-80 beats per minute in women and 64-72 beats per minute in men.
3) You exhale 78% nitrogen, 16% oxygen, 4.5% CO2 and 9.7% other gases.
4) When you inhale your rib muscles contract. When you exhale your rib muscles relax.

We think that the coughing blood, low blood pressure, and high heart rate are all effects of a problem in the respiratory system. We think that the coughing blood was caused by the pole hitting his lung allowing blood into the lung. The trachea then tries to remove the blood form the lungs by coughing. Also we think the low blood pressure was caused by the blood leaking into the lung, as the heart must pump harder to make up for the lost blood.
